Tap Tap Tap has a great parody of the oversimplified «everything is a gesture, no buttons needed» apps that have become somewhat popular recently.

The first thing you’ll notice is that we’ve killed-off the viewfinder. The viewfinder is an antiquated concept and we’re trying to get with the times here.

The second thing you’ll notice is that the shutter button has also been retired. It just doesn’t get any simpler. But how do you actually take photos? Our innovative shake to shoot system is the answer to that. We’re still tweaking this as pics are coming out a bit blurry, but that’s a minor detail compared to the elegance of the feature.

If you liked this, you'll love my book. It's called Designed for Use: Create Usable Interfaces for Applications and the Web. In it, I cover the whole design process, from user research and sketching to usability tests and A/B testing. But I don't just explain techniques, I also talk about concepts like discoverability, when and how to use animations, what we can learn from video games, and much more.

Hi. My name is Lukas Mathis. I studied Computer Science/Software Engineering and Ergonomics/Usability at ETH Zürich. I work as a software engineer and user interface designer for a swiss software company creating process management software. I've written a book about usability. It's been translated to Chinese and Japanese. My first computer was a Performa 450, my first programming language was HyperTalk, my first electric guitar was a cheap Peavey, my first videogame was a VCS 2600 and my current snowboard is from Lib Tech. I live in a small cottage in a remote part of the Swiss Alps, and you can reach me at or on twitter.
